Replace single-pane windows with double-pane equivalents. An insert for one window typically costs between $350 and $800 installed, which is less than or equal to the cost of the next option for soundproofing windows: a window replacement.Ģ. This is because the STC of a double-pane window is often higher to begin with, so an insert won’t increase its overall STC as substantially. You’ll get more noise reduction benefits by installing an insert in front of a single-pane window than a double-pane window. At the upper end, this means that a 98-decibel (db) outside noise (e.g., a motorcycle engine) is heard at only 44 db indoors (98 minus 54), which is no louder than a typical indoor conversation. On the Sound Transmission Class (STC) scale that reflects the decibel reduction in noise volume that a window provides, soundproof windows typically measure between 48 and 54-the higher the STC, the greater the noise-reduction benefit.
The most effective inserts are made of laminated glass-a thick glass consisting of two layers of glass with an intervening layer of plastic that effectively blocks vibrations.
The air space between the insert and the window keeps most sound vibrations from passing through the glass, resulting in greater noise-reduction benefits than double-pane windows (more on these ahead) alone. If you live in an environment with heavy noise pollution, such as honking car horns, wailing sirens, or blasting music from next door, utilizing soundproofing window inserts is the most effective way to reduce the cacophony. These glass inserts are installed in the window frame about five inches in front of the interior face of your existing window. RELATED: 11 DIYs for a Soundproofed Home 1.
